Hi,
I tried unlock_entity.sh, and it solved the issue. So far so good.
But it's still unclear why disks were locked.
Let me make an hypothesis: in ovirt 4.3 a failure in snapshot removal
would lead to a snapshot in illegal status. No problem, you can remove
again and the situation is fixed.
In ovirt 4.4 a failure in snapshot removal leave the whole disk in
locked state (maybe a bug?), preventing any further action.
Does it make sense?

Hi Shani,
no tasks listed in UI, and now "taskcleaner.sh -o" reports no task (just
before I gave "taskcleaner.sh -r").
But disks are still locked, and "unlock_entity.sh -q -t all -c"
(accordingly) reports only two disk's uuid (with their vm's uuid).
Time to give a chance to unlock_entity.sh?
Regards,
gc
